To all whom it may concern: I i a Be it known that we, JOHN WADEMAN,

WVVILLIA'M WADEMAN, TOM WADEMAN, and

l/VALTER l/VADEMAN, all subjects of the King of Great Britain, residing in Keighley, in the county of York and Kingdom of Eng land,jl1ave invented Improvements in Dofiing Mechanism for Spinning, Twisting, and the like Machines, of which the following is a specification;

The present inventionrelates to improve ments. in spinning, twisting, ing andthe like machines, more particularly of the cap type.

According to the present invention, meansv are provided to raise the caps into the range of a retalnlng device whereupon the real for the full bobbins is dropped and will be subsequently raised by a hinged flap on a lifting rail for the reception of the full and empty bobbins respectively. This lifting rail in rising conveys an empty bobbin into ,a cap which has been displaced in an axial line with it and willin itsmotion at the same time raise the bobbin on the spinning spindles so that spindle retaining devices moving in. a plane at right-angles to the ,motion of the said rail and pass under the flanges of the full and empty bobbins respectively and hold these in position. The full and empty bobbins are then displaced further outwards relatively to the spinning frame and the full bobbins allowed to drop on to the saidlifting rail. The end from the said full bobbin being caught from a catch on its temporary support to lie across the path of the wharle spindle so that directly the full bobbin is'received by the :1 scribed with reference to the rail and locked thereon from rotation, rota tion of the wharle will cause the engaging of the end upon it and the automatic covering-of the end from the full bobbin, the severed end being then-engaged between the wharle and the flange of the empty bobbin which is dropped on to the spinning spindle subsequent to the receding of. the cap.

This invention is more particularly de-. accompanying drawings in which Figure 1 is a diagrammatic side elevation of a spinning frame to which the invention is. applied showing the parts in one position,

Figures 2, 3, 4, 5, 6 and 7 are correspondcertain new and useful slubbing, rovs ingviews showing sltions.

Figures 2 3 4, 5 6 and 7 are various plan views showingthe relative positions of the holders with full and empty bobbins when the other parts of the machine are in the positions shown in Figures 2 to 7 respectively. I

Figure .8. is a detail showing a locking device,

Figure 9 is a sectional elevation on an enlarged scale of the spindle,

Figure lOshows a cap and spindle in a modified form of construction,

Figure 11 is a corresponding plan view to Figure 10.

v Figure 12 is a bobbin carrier.

The fibre end 1 being spun passes through drawing rollers 2, 3, edge 4, of the cap 5, of peculiar form to be spun on to abobbin 6, carried on a rail 7, driven by wharle 8 in usual manner. The bobbin-is guided by a spindle 9 mounted on a rail lO. According to the present invention this rail 10 is displaceable vertically up and down by a rack and pinion gear 11, 12. The pinion 12 can be rotated by hand or by power .at predetermined times as desired. Vfhen' it is desired to dofi' the full bobbins from the spindle the retaining device consisting of a slide 13 mounted on a rock 1 1, to be operated from a pinion on a shaft 15 is slid forward to engage the end or cut away part 16 of the cap 5. The shaft 15 can be operated by hand or power and if desired its operation may be automatically coordinated with the operation ofthe pinion 12. The cap can thus be supported in the position shown in Fig. 2, whilst the spindle 9 is dropped down into the position shown in this figure to bring the bobbin 6 clear of the cap 5-. Meanwhile the bobbin reserve holder is operated from the position shown in F igure 1 to that shown in Figure 2. This reserve holder comprises a squared shaft 17 mounted in a support 18, mounted on a rack bar 19, moving in guides 20, on the spinning frame, which rack bar 19 is operated by a pinion 21 either worked by hand or power or automatically operating in co-ordinated relationship with the operation of the shafts 12 and 15. As the spindle 9 is therefore lowered into the position and under the lower,

shown in Figure 2 the rack bar 19 is slightly raised. The shaft 17 is then rotated by means of hand grip 22 or againautomatically to swing the spindle23 ca'rryingthe spare empty bobbin 24: into the operative position when it will lieadjacent to the lull bobbin 6. The slide 13 is then displaced; further outwards from the spinning frame into the position showrr'in Figurei3 until the cap 5 lies axiallyabove the reserve spindle 23. The spindle 23" and wharle '8 are then simultaneously moved upwards until thebobbin liesuwit'hinthe cap 5." In th'is position the holders 25, 26 for the einpty and lull bobbins respeetively are slid' sideways, that is to say laterally acrossthefraine 1111tll tl1(3yCOHl B under the'bobbins'2 l and 6" respectively as-willbeseen" from FignreB The spindles 23, wharle S and tube 32 are then again dropped by means" of the rack bar 19' until theparts take up the position shown inFigure 3. The slide- 13* which supports the holders 25 and 26 is then slid still furtherawaiy fror'n the flameof the "i'aehine until the full bobbin 6 lies over the spindle23l v V The rack '19" 1S tll'lii raised' until th fl'l ll bobbin is taken up on the spindle 23, where: upon the holder'26is displaced laterally on us guide rail 27, independently ofthe holder New when-the spindle 23 wnrbe lowered by eans-of the rack bar" it willtake with it the full bobbin 6, the lowe'f' fiitnge 28 on which will be engaged by a spring eaten 29 to; revent"unpredetermified' release of the fullldobbiii from the" s indle as: This eaten is'howevernot essential-tn the operationof'the device." i The squared shaft 1? is then wasted bymeansoi' ahandle 22 or otherwise intdthe position shown in Figure 4;; It will be referred'to pmvidesome leaking devise: for, this shaft; This 'can' be obtained-by means of astop such (Figure 8) enga ingwith arail 31, disen agement neinqy ro vided by moving the handle 22 slightly sideways or laterally until thesto eotomes out" of engagement with the stop ran- 31.

The parts are then in the position suit able for hal'clling; tlizitis-td say, odnnection of tliespnn end to theeni pty bobbin; The shaft 17 is turned to the positibii Snow in Figure '5 so that th'e endl liesin thepath of the drivingtiiloe 32 on the spindle" '9. The slide 13 is thenslid back into theposi tion shown in Figure 5; "whereupon the holder 25 is slidon'to its guideran 34 lateralli to tree this from] the 'bobbin23 as shown in Figures 5; 6?. The'empty bobbin 24 then fallson to the dri vingtnbe semacoines seo'iirely into engagement with it" whilst the end'l will be lockedbetween the bottzim' flange of thebbbldin 24 will the wharl'e. The shaft 17 will be"' n etinwliile turnedto the position shown inFigure 4:- in

which the full bobbin 6 engages with a pin 33 which prevents it "from rotating on the spindle 23. Consequently directly; the wliarle 8 comnfenoes to rotate the ens will be severed between the full bobbin d and the fresh emptybobbin 2 1. H

Spinning can now commence directly the bobbin 2% is brought into range of the spindle cap ehrwhich can then be released from the holder 13.
